PURPOSE:To shorten a copying time by copying alternate one-surface originals in one direction of copying paper from the tail page and then copying the remaining originals in the backward page order on the other-side surfaces of the copying paper where the 2nd page from the tail page or the tail page according to whether the number of the originals is odd or even. CONSTITUTION:Alternate one-surface originals X are copied on one surface of the copying paper Y from the tail page and the number of the originals X is counted. When the counted number of the originals is odd, nothing is copied on the other side of the copying paper Y where the final page of the original X is copied and the remaining originals X which are not copied when counted are copied in the backward page order on the other-surface sides of the copying paper Y where the 2nd and succeeding originals X from the tail page of the original X are copied. When the number of the originals is even, the remaining originals X which are not copied when counted are copied in the backward page order on the respective other surfaces of the copying paper Y where the final age of the original X is copied. Consequently, the number of the originals need not be counted and the formation time for a both-surface copy can be shortened. |
